Joab is a biblical masculine name of Hebrew origin, meaning "Yahweh is father". It is derived from the elements יוֹ (yo), referring to the Hebrew God, and אָב (ʾav) meaning "father". Biblical Narrative According to the Old Testament, Joab was the son of Zeruiah, a sister of King David, making him David's nephew. He served as the commander of David's army and is portrayed as a skilled and ruthless military leader. In separate incidents, Joab killed Abner (to avenge his brother Asahel's death) and Absalom (David's rebellious son). These acts, along with his later support of Adonijah over Solomon, led to his execution by Solomon when the latter became king. Cultural and Linguistic Context The name Joab appears in the Old Testament as one of several theophoric names combining a divine element with a familial term, emphasizing a relationship with God. The root Yahweh appears as a prefix (Yo-) in many Hebrew names. Variants include Yoav in modern Hebrew, Ioab in Biblical Latin, and Joabe in Brazilian Portuguese.
